70 all 'whom t may concern. i .-Be it knowny that Ll'ilvlanoms H. Loom, wooo, a oitizenoof .the United States, and 'ifresident oi? :the borough of Manhattan, cit-y,K foounty', -and-iState of-.New York, have inlvented certainfdre'wl ando-useful Improveiments in Type-Writing'Machinesa oi' which o fthe followingis a; specification.

My invenluon relates more particularly to lftabulatingtstop. vsetting; devices wherein a plurality offtappet stops, a letter space dis- *tance apart, is rmounted on the typewriter carriage and one or `inore of said. stops may be ...turned or flnovedvinto position toeolaoperatewith thefusual-ly actuated tabu- `dater: stops.

f The object otimyzinvention is to simplify the construction and* embody the device in com act forni. yMost of Athemechanism is 2CV-.learned by the. typewritercarriage, only the f .,setting linger, a single piece, is mounted=on a tztedfpart et the machine. f This arrangementsilnplifies the movementsnecessary to. Betr-the tappet stops in the -various colum- 2o-narl positions desired, and permits resetting' i: lthe stops to their inoperative position by a \3 1 single movement of a' lever without any @manipulation whatever of the typewriter "marriage, These'and other objects will be Sofinore readily apparentfrom the following 1i descriptontaken in connection with the ac- A l coinpanying drawings in which-- f Figure l is a top plan view of my device; Fig. 2 is a rear :view yt' the saine; Fig. 3f represents a section at --3 of Fig. l.; Fig. 4 is a similar section at`fl-4 of Fig. l; Fig. 5 is a view showing the operating lever end of the device; Fig. Gyshows an end view I- when the lever is operated for setting a sto and Fig. 7 shows the lever when operate for eliminating or restoring set vstops to in. operative position; Fig. 8 1s a view of one of the stops and Fig. 9 represents the construction of the spacing?r elements.

The lorrn of the device shown is adapted' to be atached te the well known Underwood typewriting machine provided with a denominational tabulator but it will 4be unl"derstood that the device may be attached to 5e any'standard typewriting machine and used in connection with any of the usual forms 'oft/abulating'.devices.l Only fragmentary portions of the typewriter carriage and key actuated .tabulator'stnps are here'shown,

`since .theconstruetionand operation of these ,parte fare well understood.

.-.lnthe `drawingsyh` represents the bracket yor vease Supporting the .usual key actuated denominationalsteps 1.

B represents a portionof the typewriter carriage to which the tappet stop bar isnt- .tached by means of. brackets 2 and 3. AIn the present instance, thwstop bar is provided with a pluralityofi stops el, each of fwhicl'r; as indicated in Eigs. 3, L and 8,-is provided. with two radially extending lugs or..pro.jections 5.and G integral with a s )lit .ring which forlnsthe body of the stop. he airing is split at 7 and the ends thereof sprung apart laterally so; as to act as. a friction .spring washer to hold the stop in either 0fv two. positions as more fully hereinafter explained. The stops are inountedon a` shaft 8 which is mounted vto turn' in thebracket supports 2 and 2l and spaced apart by:n1eans -ot any suitable spacing elements such as .that indicated in Fig". J of the drawings. .'lhe disk like, spacing' elements i) are preferabl provided with hub-like projections l0 anc 111011 each side, whicl1,a1'e arranged t0 interloclc with adjacent spacing elements so .as to leave a space between theeleinents of substantially the thickness of the stops il which are 'placed therebetween. This construction is clearly indicated in Figs. l, 2, 3 and 4. 4The spacing elements at each end ofthe series are shown as ot' greater thickness and are pinned or otherwise secured to the shaft 8, hence it will be seen that the interlockingz,r arrangement of the spacing elements will prevent these elements from .turning independently of the shaft 8, which latter, in this case isshown as tubular, the tubular construction being merely` forthe purpose oi' reducing the weight., The stops and spacing elements are mounted alternately on the shaft 8 and a suflicient number oi stops .is employed to` cover the entire width of the tabnlating field, the stops being a letter space distance apart. From this arrangement it will be seen that the split ring or washer portionof the stop 4 will rub against adjacentspacing elements yand trictionally .control theA movement of .the stop .when the shant- 8 isrocked, or moved .in either direction as explained-later. The shaft 8 is mounted in. thebrackets 2` and 3 so as `to bring the stops 5in plminlitymo Los the actuated tsbnlator stops l. ln the normal i'iowever, the stop lugs 5 stand the po dion indicated by the iii-st stop `n io'. 31, that is, with the stop lug 5 out of `the l'ield or path of the key actuated stops Ii..`

Attached the fixed lrame il of the tabulator stops or to other lined part oi' the machine a bracket 12 which is secured in s ch. position that the projecting iup,l or iii v stands over the stop lugs of the iries ol" tappet stops. This finger is only of suliieient `width or thickness to eng one et the stops o when. it is desired to s the saine into position to cooperate with the iLey-actuated stops 1. Extending parallel with the shaft 8 and over the series oit stops a bar ll which has one edge thereo'lf located ,in a substantially radial ne, passing tluougjh ihe axis of the shaft this edge ot the bar or plateV 11i being adepti l to contact with the ings 6 of the stops when the stops are to be reset or nii/red lo inoperaiive position as hereinafter wplained. ile 'lo may be secured to or inounleifl upon. the bar lll in any suitable 1er and so located as to indicate the letter space position of the stops with relation to the sel ting linger 13; an extension or pointer lo, secured to said Enger and extendingl overy the scale 15, being` adapted to `facilitate i'eiulingj the position.

'Ils previously indicated, the shaft 8 is adapted to be rotated a limited amount in either direction and to carry with it the itrictionaily mounted stops lA-"5. A lever 17 is connected to the end oi? this shaft ifor the purpose of rotating the same a limited ex tent in either direction. "lhe normal position oll the shaft and the level' is indicated in illigr. 5 which Vgosition is n'iaintained by a springi,f '18 which is coiled about the hub of the lever. ioth ends o't the spring` 18 are active, one end {hissing} back olv pins 1S) and 20, and the other end back of pins Q1 and 22. iildjacent to the hub 23 ot the lever 17 is a disk 2i or other suitable support attached to the bracket il which supports one end. of the sha'l't 8 lhc pins 2O and Q2 are secured to and project outward irom the dist: 2li into the path of the ends ol the spring; 18. 'lhe pins 19 and 2l are secured to the disk-like portion ol" the hub Q8 and project inward into the path ol the ends of the spring 18, the ariuulgement beine' such that in normal position the lour pins .i9 and 20, 2l and aro r-.uimtantially Vin radial lines passing' through the'eeuter of the shaft 8 as findicated in ilig. 5 oi" the drawings. 'i`he object ot this arrangement is to have the single swing act to hold the shaft 8 with the stops in the normal position indi cated in llio'. 5, and at the same time permit a, movement ol the .shalt in either direction. the springacting' to restore the shaft ons to the normal position whenI the lever 17 is released. lt will be readily understood that this function ot the spring and the various pins may be performed by springs and devices otherwise arranged, and I do not wish to be limited to the particular structure shown. Since the spring 18 not only acts to hold the shaft in the normal position, but is used to move the shaft from either direction back to normal position after having; been displaced by the lever 17, it will readily be understood that when the lever is released 'and the shaft and associated parts returned to normal position under the action ot the spring 18, there will vbe some tendency for the shaft to overthrow or go beyond vthe normal position. To prevent this overthrow, when the shaft is returning to normal position under the action ol either end ot the spring- 18, the lever 17 is not secured directly to shaft 8, but is pivotally secured at to an arm 26 extending from the hub 23, which as previously indicated, is secured to the end of the shaft 8. 'lhe lever 17.l` is provided with an enlarged 90 or elongated hole 27 through which a pin 28,

projecting from the outer end of the arm QG, extends. r1`his pinand slot connection between the lever 17 and the hub 23 permits ot a limited amount of lost motion of the 95 lever in either direction before it can nieveV` the shaft 8 against the spring 18. This lost motion is provided for the purpose of rock ing` the arms 29 and 30 out of or into the extend from the fixed disk-like bracket 24 inicthe path of the arms 29 and 30. The aruis'QD and 30 are so arranged with relation to pins 3l and Sthat when the lever 1.7 is pushed downward, the arm 29 will 10'5 clear the pin 3l and the rock-shaft 8 can bev turned a limited amount as indicated by the position of the lever in Fig. 6 of the drawings. lVheu in this position, it will be seen' that the arm 30 is in the path of the pin 32' 110 so that when the lever '1.7 is released and, under the influence oiL the spring 18, the shaft is returned to normal position, the arm 30 will strike the pin Sl'and prevent overthrow olf the shaft 8. Likewise whenayg, the lever l? is moved in the opposite direction as indicated in Fig. 7. the lost motion thereof will permit the arm 30 to clear the pin 32, while the arm 29 will be brought into the lield of the pin 3l, so that when ,ma the lever is released and tho shaft and arnts are rotated back to normal position by the spring i8, ilhe arin 2S) will contact with the pin 31 and prevent overthrow in this direc tion. lt will readily oe apparent that othe` lniitable means for preventing overthrowthe shaft may be employed`.

'ihe operation of the device may` berlre'adn ily understood from thel'oregoing descriplion, but it will be well toindicate the gen-A field of the respective pins 31 and 32 which 19.3

eral pian of operatingjr the device in connection With the typewriter. With the stops all in normal position, which afs previously stated, would be the position ol? the first stop shown in Fig. 3 of the drawings, the oarriage of the typewriter is moved by hand to the desired columnar position as indicated by the front or regular scale and pointer ol. the typewriter. ln this position, the lever 17 is pressed down to the position represented in Fig. fi oit' the drawings. This will rotate or roel: the sha'it 8 together with all. of the stops 4 except the one standing' in the plane oit the stop setting' finger iii-i3 which Will be prevented from rotating with the shaft by Contact oi the lng1 5 with the pro- 'l`hns the individual stop ft in Contact with the settingl finger 13 is rotated to operative position with relation to the shaft 8. When the lever 17 is released, the

. spring; 'i8 will restore 'the shalt to the nor nial position indicated in Fig. 5, which movement Will carry the stop projection 5 of the stop which has been acted on by the Stop finger i3 into the path of the hey actu@ ated tabulator stops fl as indicated by thc front stop in the .section in Fig. l-l ot the drawings. This operation may he repeated by moving, the typewriter carriage to other columnar positions as required, otter which the key actuated talmlator stops l may he operated in the usual manner, `When itwiri desired to change the colnn'lnar errainre ment ol the stops in use, or in other worde, to set np a dill'erent combination olz stops, ally the set stops or stops in operative posi tion may ne restored to normal inoperative position by rocking the shaft 8 in the opposite direction. rllhe lever Il? is then lifted to the position indicated in Fig. 7, thereby bring-ging the lugs 6 of all stops set in operative position into contact with the edge of the bar or plate 11i which serves to hold these stops from movement, as the shaft 8 turns thus turningl or bringing all the stops back to the normal inoperative position with all the logs 5 out ot' the tield ol. the hey actu ated stops l. After restoring the stops to normal inoperative position, n new combination oit columnar stops may be not .in the manner described and restored to normal inoperative position, the operation'beiner repeated frequently as desired. The frietion between the shaft Ei and the stops -flis only sutlieient to prevent the stops 'from boing displaced during the normal operation of the typewriter.
